Reactjs React-克隆存储库npm安装不工作

我在github教程中有一个重要的存储库，当我克隆这个存储库，然后npm安装时，npm start不起作用。这是我在终端中看到的：

react-scripts start

sh: react-scripts: command not found
npm ERR! file sh
npm ERR! code ELIFECYCLE
npm ERR! errno ENOENT
npm ERR! syscall spawn
npm ERR! 01@0.1.0 start: `react-scripts start`
npm ERR! spawn ENOENT
npm ERR! 
npm ERR! Failed at the 01@0.1.0 start script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

npm ERR! A complete log of this run can be found in:
npm ERR!     /Users/kacperfaligowski/.npm/_logs/2020-03-19T01_09_33_794Z-debug.log

试图解决这个问题，但两个小时内什么都做不了。我的npm版本是-6.4.1。 我必须这样做，因为我无法完成教程的下一步。 请帮帮我。谢谢

package.json：

我的npm安装无法安装存储库中的所有依赖项。 我修复了使用以下方法全局更新npm的问题：

sudo npm install -g npm@latest

请为package.json文件添加一些代码我现在又添加了一件事，repo是否有package-lock.json或warn.lock文件？哪一个？这两个都有吗
